Are dlc displayed at nintendo treehouse?

I'm honestly not very familiar with nintendo tree house e3. Last time I payed any attention to it was in 2013.

Does this announce dlc? Like an acnh update?

Don't get me wrong, nintendos e3 was definitely the best in my opinion, but I wanted to see acnh content and other dlc.

I believe they revealed the 3DS game Metroid: Samus Returns as a whole during one of the previous E3 Treehouse. So it's not impossible.
